Hemp.—The true hemp-fibre, to be distinguished from Manila hemp and Sisal hemp, which will be con- sidered later, is derived from Cannabis sativa, an herb with much the same range as the flax-plant, grown most extensively, perhaps, in Russia and Italy. It is a strong fibre, though Ifess pliable than flax, and is used for cordage, sail-making, and the manufacture of certain other tex- tiles.

The hemp-fibre cell very closely resembles that of flax in its microscopic appearance, being of the same size and general shape and showing the same knots and swellings. It may be distinguished by two characteristics. First, the canal, like the cell, is elliptical in cross-section, so that while the cell on its narrow surface cannot be distin-.
